unable to find ImageView from the inflated layout

I've created a layout and I am trying to binding to its IDs.

I have managed to bind to the TextView's but I was unable to find imageView id for some reason.

 public FeedsAdapter(@NonNull Context context, int resource, @NonNull List objects) {
        super(context, resource, objects);
        this.myFeeds = objects;
        this.activity = context;
        this.layoutId = resource;
    }
    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        LayoutInflater inflater = LayoutInflater.from(this.activity);
        convertView = inflater.inflate(this.layoutId, parent, false);
        Feed currentFeed = this.myFeeds.get(position);

        TextView authorTextView = convertView.findViewById(R.id.author);
        TextView dateTextView = convertView.findViewById(R.id.date);
        TextView contentTextView = convertView.findViewById(R.id.content);

        ImageView imgImageView = (ImageView) convertView.findViewById(R.id.img);

        authorTextView.setText(currentFeed.getAuthor());
        dateTextView.setText(currentFeed.getDate());
        contentTextView.setText(currentFeed.getContent());
        return convertView;
    }

ImageView imgImageView = (ImageView) convertView.findViewById(R.id.img);

this line return me an error that he doesn't know what is R.id.img

the is the layout XML:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    <TextView

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.045"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_bias="0.138" />

    <TextView
        android:id="@+id/content"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.099"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_bias="0.845" />

    <ImageView
        android:id="@+id/img"
        android:layout_width="118dp"
        android:layout_height="106dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.091"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:srcCompat="@drawable/a150" />

</androidx.constraintlayout.widget.ConstraintLayout>

btw, I'm looking for an option to put a placeholder for the imageView without put any src is it possible?

Thanks!

This can happen sometimes when the cache in the editor gets out of sync with the resources file. The best way to fix this is by going to File > Invalidate Caches/Restart
